“We must learn and we will learn.” With this phrase, David Hilbert, one of the greatest mathematicians of his generation, called upon his colleagues to solve the unsolved problems that were troubling the mathematical community at that time, believing that in mathematics there is nothing "dark" and unsolvable.

With this book, we aim to show the student that in mathematics there are no dead ends and difficult paths; with the right guidance, we can approach all the problems that arise and tackle them successfully.

Each chapter consists of sections that follow this structure:

• Complete theory in the form of questions and answers, accompanied by examples
• Exercise methodology with solved applications, so that the student is equipped with the appropriate "tools" to solve exercises of any level.
• A multitude of unsolved applications and questions, covering all the forms that the student may encounter during the school year
• Evaluation sheets for the complete assimilation of the material
• All the topics from the Question Bank, at the end of each chapter.

Believing that success ultimately comes from organized and methodical repetition, we have included at the end of each chapter, and at the end of the book, review topics and exams structured in such a way as to cover all the cases the student dealt with in the chapters taught.
